A stiff, plastic tube, usually "L"-shaped, that is attached to the Racking Hose to make Racking easier. A protective cap is placed over the lower end of the cane that allows liquid to be drawn into the cane from above rather than below while keeping most large solids out. The cap allows the tip of the cane to be lowered close to the lees without unduely disturbing them. The lower tip of the Racking Cane should initially be held about midway between the suface and the lees and gradually lowered as the volume decreases due to the siphoning.
